I am trying to set up a new cache pool with two NVMe drives (Crucial P5 500GB).
I have this Mainboard https://www.gigabyte.com/Motherboard/C246N-WU2-rev-10#kf and got this PCIe-Card https://www.delock.de/produkte/G_89045/merkmale.html?setLanguage=en . Long story short: It does not work, Unraid does not show me the new drives when I want to assign them to the new cache pool. I already changed the bios setting "CPU PCIE x16 Switch" ("Allows you to determine how the bandwidth of the PCIEX16 slot is divided. (Default: 1x16)") from [1x16] to [2x8] as well as [1x8 & 2x4], which does not make any difference.
What am I doing wrong here? Please tell me if you need any more information. And I hope, i put this into the right category. If not, don't hesitate to tell me. Thanks.
